“Our planet is not in the grips of a clash of civilisations or cultures. It is the battleground of a decisive struggle between two ways of thinking. There are those who declare that there are no facts, but only interpretations – so many acts of faith. These either tend toward fanaticism (“I am the truth”) or they fall into nihilism (“nothing is true, nothing is false”). Opposing them are those who advocate free discussion with a view to distinguishing between true and false, those for whom political and scientific matters – or simple judgement – can be settled on the basis of worldly facts, independently of arbitrary pre-established opinions.”
